To overcome shortcomings of Exact Matching Method EMM and Substitute Description Method SDM, an Ontology and Concept Lattice Based Inexact Matching Method OCLIMM is introduced. This method, firstly, describes resources information with Ontology languages to get Resource Ontology Descriptions RODs; then, infers Substantiality Concept Lattices and Property Concept Lattices from ROD; lastly, computes Formal Concept Distance between the required resource and each of existing resources based on Concept Lattices, and selects resources by formal concept distances and thresholds. The results of experiments indicate: firstly, OCLIMM improves EMM at the aspect of matching count when inputs are same, and the more count of input properties is, the more degree of improvement is when their parameters are uniform, i.e., OCLIMM can utilize fully resources discovered than EMM; then, OCLIMM is averagely 4.55 times as large as EMM at the aspect of matching count even if the threshold is zero; at last, OCLIMM can adapt more smartly than SDM to the condition of lots of resources and properties being in pervasive computing environment.
